Most Popular Manual for 2017 GMC Sierra 3500

After reading lots of reviews on several mirrors, I decided to buy the K-Source Universal Towing Mirrors. Oh how I wish my truck could use the ones that slip over the existing mirrors! I was prepared for a fight, based on reviews, and boy did I get one! I truly needed a third hand when figuring out how to attach these. I was bound and determined that I could do this on my own. No mirrors were going to defeat me! I did ask my husband to come look at them. He started to help but I shewed him away. After a lot of words that don’t normally come out of my mouth and a few tears, the first one was on! Then I had to go do it again in the other side! I’m pretty sure the neighbors heard me yelling. But I persisted! Lo and behold, this 67 year old Grammy did it! It was clear they would not stay on by themselves, so I grabbed a couple of bungee cords and wrapped them around the housing and they aren’t going anywhere. I have left them on my truck. No way I’m going thru that every time we return from camping. I will take them off at the end of camping season. Delivery was really fast. I was disappointed that one box was brand new and the other was smashed and taped, an obvious return. I would have been very unhappy if there was a piece missing or if something was wrong since this was my first purchase with etrailer. Overall, the mirrors work, they do not shake and I find I don’t use the truck mirrors now. Very happy with my purchase.

Fitted on 2024 Toyota Tundra SR5 CrewMax Cab w/ Stock Mirrors No vibration issues with either mirror. Turned left and right side clip on mirrors vertical so the did not overlap truck mirrors. Right side no problem with attachment and was able to adjust truck mirror. Could also see father back along right side of a 24’ travel trailer than just looking in truck mirror. Don’t expect to see behind on right side any vehicles tucked up close. Left side mirror attachment had to be modified so I could adjust truck mirror without interfering with clip on mirror lower L “hooks”. I put a rubber blocks under the lower L hooks so they were low enough to get under truck mirror glass yet still clamp to truck mirror housing. A picture tells the story. 7,000 km/4,200 miles later and neither mirror has loosened or moved. No vibration or distortion. Yes, I ran 2 zip ties as safety “chains” from the back straps to truck mirror arm just in case, they’re barely snug. I recommend these.

Mirrors work exactly as intended, greatly improving rear vision when towing our pontoon behind our 2014 Tacoma. Store nicely in the compartment under the rear seat.

Excellent product. Easy to put on. Took them off, put them in my camper storage. Next trip out, when I put them on, I did not even need to adjust them! The mirrors are slight contour and slight magnification, which makes them easy to see. There is virtually NO vibration during travel. (I have had others that shimmied so bad you could not see a thing.) I flip my driver side mirror in frequently to check my mail box, so it is not very stiff. So I ran a small bungee from the clamp to the grill under my hood. Did this for both sides. My driver side flipped in when traveling at interstate speeds, so I put a second bungee on it. Fixed the problem. Allen bolts at top of clamp are rusting after 2nd use. All in all though, I am very pleased with this product and it is well worth the money spent. It is the only product I could find to properly fit my 2011 Toyota Tacoma, because it clamps on the mirror frame and does not rest on my truck mirrors. Great Product!

Look good and very adjustable. However other reviews complained of mirror falling off. In past year, mirror fell off a few times. But I zip tie them to stock mirror and try to remember to check mounts when traveling. It appears wind and road vibration loosen mount screws and they hold on by about a quarter inch lip.

So far, so good. I received the CIPA mirrors today and immediately installed them. Installation instructions are straight forward. I took a test drive of about 15 miles; there was no noticeable shake or rattle and the mounts did not loosen. As with factory curbside mirrors, objects are closer than they appear with the CIPA mirrors, too. Our first trip towing is a couple weeks from now. I will update my review after the trip.

These worked great on my wife's Yukon. Installation instructions were clear and direct. They held up very well traveling 75 mph down the interstate; No jostling around or coming loose. I loved the additional two mirrors. Having the three total different angles while pulling a trailer was extremely helpful. Would highly recommend this setup.

Tried 3 other styles of tow mirrors for my 2019 Jeep Grand Cherokee but nothing would fit properly until I bought these. Love the ratchet style clamping system. Fit perfectly. Great product for my SUV.

After years of replacing mirrors from other sources I purchased a pair of these. There fantastic, plenty of adjustments. Got covid on vacation, really sick and did not properly install mirror. Not broken but scratched badly from asphalt at 55 mph. Purchased a replacement, scratched one is my spare.

These mirrors are good, but not great. I bought these because nothing else fits my 2004 Ford Expedition. They allow me to see around my trailer much better than the factory mirrors, but the have a slight vibration driving down the road. They also make a very noticeable noise from the wind going between the factory mirror and this product. Finally, one of the straps came off when I tightened it a bit too much, but didn't break. The picture below was done in humor (I took my trailer through a drive through, thought it was really funny, and had to take a picture. The picture is a good shot of the mirrors.)

They are fine for the price but hard to adjust the mirror itself after installation. I’ll be installing the bigger factory trailer mirrors pretty soon.

They appear to be as advertised, well made and should be easy to install. That may change once the rain stops and I am able to actually install them and then use them during the towing operation of our trailer. But i feel pretty confident they will be very helpful.

I have a 2016 Silverado 2500 HD LTZ with factory mirrors including heat, turn signal and electric adjustments. Have been towing a 24 foot Travel trailer and the factory mirrors are adequate. Am used to swerving a little to see behind the trailer before changing lanes. Am now going to tow a thirty foot trailer and decided the mirrors would not do. Looked for an oem towing mirror but was shocked by the price. $[XX] plus for one that has all the functions of the LTZ mirror. Looked around, watched videos, read reviews and decided to puchase these mirrors. Got them today and they installed in a snap. Have yet to use them but will be shortly. Initial impression is that they will provide the extra vision needed to pull this trailer. Only complaint was the condition of the package received by USPS. The product was shipped in the manufacturer packaging which was probably not a good choice. Fortunately the mirrors were undamaged as can be seen in the photos. In any case, the mirrors fit and seem to be well constructed. Hence the five stars. Time will tell if I made a good choice.

These could be the best mirror extensions I’ve ever owned. They are totally worth the cost. Scratching of the factory is an issue during installation and dismount. I used helicopter tape to minimize the problem spots.

Purchased these to tow a rented travel trailer. They attached securely and provided just enough extra width to see down the sides of the trailer. Mine have 1000 miles on them, no issues.

Once modified slightly, these mirrors work great. For our Chevy Express Van, the collar and hole for the cinching nut needed to be adjusted so the threads on the tightening clip don't have a 20-30 degree side stress on them at the nut. Other than that, they're very good mirrors with little or no vibration while driving. The face of the collar had to be beveled and the hole slotted to allow the nut to angle off correctly. The photos show after modification. etrailer has submitted the photos to the manufacturer for consideration. What easy folks to work with at etrailer.com.

Fit my 2019 Chevy Suburban perfect. Easy to snap on/off without any tools or adjustments. I have a 7.5' wide enclosed trailer that I pull some dirtbikes in. It works perfect. Gives me just enough to see further behind me. Not sure how helpful they would be for an 8' wide box. Works for me though. I definitely recommend them. Blend right in and look clean too.

I purchased this because there wasn't an alternative side mirror extension that form fitted my Yukon Denali side mirrors. All of the other units I tried looked like UHaul add ons. They vibrated while driving and just looked tacky. These fit nicely. Are a little difficult to snap on but not prohibitively. I do remove these when I'm not towing my camper so ease of removal and installation are important to me.

Pros: Very easy to install. Will fit on almost anything. Cons: Bit of a challenge to adjust the in/out tilt on fixed mirror housings. Would like a little more height, but it's OK. This is a good solution for the casual user like me. Installation is painless. If you need more control over height or tilt, this is not for you.

I bought the trailer mirrors for my Jeep Grand Cherokee to pull my pull behind trailer. See pictures. The mirrors attach easily and securely and shake very little when driving. I need them mostly when backing up and I can see where the trailer tires are going. The mirrors do not adjust easily but when you do they stay in place. What I especially like is the size of the mirrors and having two independent mirrors.

The good: inexpensive; decent quality materials The bad: doesn't hold it position very well during extensive or high speed travel - you have to readjust at nearly every stop for gas on a trip. Conclusion: It is worth the money due to its fair price.

Purchased a pair for our 2017 Jeep Grand Cherokee towing a nuCamp 400 from FL to AK and back. Three months and around 16k miles. Pros - other than an adjustment the second day, I never had to adjust the tension straps again. They were easy to mount and did not interfere with our mirrors folding inward. They weathered three months on the road without issue though I was beginning to worry about the straps becoming brittle. I noticed this once I removed them. Had I kept them, I would have used some silicon to rejuvenate the rubber. Cons - the only con is they shake. They shake to the point that sometimes I couldn't distinguish what exactly was behind me. I knew there was a vehicle, but the distortion from the vibration prohibited me from getting a clear view of exactly what was behind us. Impressions - they worked for our trip but I knew I would want something else for our next long trip, so we invested in a Furrion Reviewing Camera.

THE PRODUCT IS GOOD BUT NOT GREAT. THE ENTIRE ORDERING PROCESS AND QUICK DELIVERY WAS EXCELLENT.

I went right away to try them on my truck. I have a 24 Denali ultimate 1500 Denali and I have a couple of cameras on my side mirrors. The straps are easy to maneuver around the cameras to avoid issues there. Good snug fit I have not taken it out yet to test these in real road conditions but so far so good.

great addition to the factory mirrors for towing. Simple to install and remove with absolutely no damage to the factory mirrors. The adjustable mirrors stay in place well. I now leave these towing mirrors on the truck , my wife likes the extra view even without the camper hooked up. The mirrors allow all factory lights and sensors to function properly.

Snap on Snap off Hold perfectly, come with storage bag for when not using. This is a great product Have used all summer and fall. put in bag for winter and using again I would defiantly recommend this

The company was fast and gave lots of updates for shipping. Once i received product my concerns were met. The straps are BARELY long enough to connect around my mirror. Once it is straped properly the tension on straps pulls them right out of the retaining clip. I ordered these because i have a 11 silverado just like what was in the product pictures. Save your money and get something else because theres no way these will make it down the highway they will barely stay on just sitting here. Kinda disappointed because i bout these for our first camping trip this weekend but these will not work. Seems like a good company just crappy product.

Thank you for the easy shopping experience and delivery.

They are very easy to install and remove when parked for extended periods. Costumer service was very helpful with getting me the correct marrows.

Great product! I use them on all my trailers as well as my travel trailer. This is actually me second set...the first got destroyed by a hit n run and i could not live without them!

Haven’t had a chance to use these but did put them on my truck to get them adjusted. Easy to install and look like they will give me good coverage.

The Universal fit towing Mirrors-THis is easy to put on and off and gives great visibility when towing our boat

Fit perfect !!!!!! Excellent quality.

I had ordered a set of strap on tow mirrors and was dissatisfied with the fit. They were easily returned and I decided I wanted this pair for complete change out. These mirrors are beautiful and large. They extend approximately 23" from the attachment point to the vehicle. It fits in the same vehicle footprint. They look really good and the lower mirror is a wide angle for added view.

Parts came in one day early. Prefect match for my 2015 3500 HD Chevy.. I called my order in and the lady that placed my order was outstanding.. She was very customer friendly. Thanks and I will be using etrailer again.

These mirrors fit perfectly on my 2018 Silverado. They give me a much better view of the trailer and adjacent highway lanes. I would have given it 5 stars but the right mirror is difficult to adjust. I had to go from drivers seat to side mirror and back many times to get it to where I wanted. That's probably just part of the regular process. I don't know how that could be improved. It attaches and is removable very easily.

Easy to install, and works as advertised. Shipping was fantastic. Thanks etrailer.

The mirrors help me tow our Lance trailer safely. The adjustable mirrors benefited with a touch of dry lubricant on the joint inside the housing. Emily at etrailer was very helpful!

First set had a factory defect. The hole for the tension knob was not threaded. Replacement sent was also a defect, the mirror panel swivel was un-adjustable. Spend the extra money and get the correct OEM ones for your vehicle.
